A DB2 redundant node can be set up with data replication. 可以设置DB2冗余节点来进行数据复制。
Upon failure of the primary node the redundant node takes over. 在主节点发生故障时,冗余节点可以接管。
In the algorithm, every node independently judges whether it is a redundant node based on its local-perimeter coverage. 该算法中每个节点基于局部圆周覆盖情况独立计算自身是否为冗余节点。
This paper proposes a handoff protocol based on dual-link. This protocol makes use of redundant link based on the scheme of pre-triggering to realize seamless handoff of mobile node. 该文提出了一种基于双链路的切换协议,该协议在提前触发等机制的保障下采用链路冗余的方式,实现了移动节点的无缝切换。
Taking redundant control of materiel grasp and sending system as an example, output of redundant node was tested, output of fault controller was replaced by estimate output to renew function of controller, and realize self-diagnosis of the system. 以物料抓送系统的冗余控制为例,对冗余结点的输出进行检测、用估计输出取代故障控制器的输出使其功能恢复,实现系统的自诊断。
Dynamic cover problem is in this case, by carefully scheduling the activities of the node, so that redundant nodes alternate work. We can use this kind of node deployment to extend the survival time of wireless sensor networks. 动态覆盖问题就是在这种情况下,通过对节点的活动进行精心调度,让冗余节点交替工作,可以利用这种节点部署的冗余性有效地延长无线传感器网络的生存时间。
Through the data fusion of the three layers, it will be able to eliminate the redundant data in the network, save the node energy and then extend the life cycle of the WSN. 通过这三层的层层数据融合,将能够有效地消除网络中的冗余数据,节省节点能耗,从而延长WSN的生命周期。
First, enhancing the density of distribution of the nodes around the gateway. Second, using the redundant gateway node. 方案一是,提高网关节点周围节点分布密度;方案二是,采用冗余网关节点。
The SGA is the free-location coverage algorithm in two-dimensions ( 2D), which has advantage in coverage percentage and redundant node rate, but is bad in energy consumption. SGA是二维空间中的一种覆盖算法,该算法不需要节点位置信息,覆盖率或冗余节点率方面也有一定的优势,但是没有考虑节点的能量均衡消耗问题。
In order to find the redundant nodes and sleep it, the algorithm deploys a sensor node at each matrix point and then tries to remove each node and then evaluates whether the area still maintain coverage. 算法在每个矩阵点上部署一个传感器节点,尝试删除每一个节点并评价区域是否保持覆盖,从而找出休眠节点,并休眠冗余节点。
When this relaying node fails, some redundant node can take up its responsibility, thus strengthens the survivability of the network. 在中转节点失效时,冗余的节点可以接替失效节点的工作,使网络具有抗毁能力。
The main contribution of this paper is as follows: 1. For IP-based low-power lossy network routing protocol RPL ( IPv6Routing Protocol for LLN), existing algorithms transmit a large number of redundant data, and waste limited node energy resources. 本文的主要贡献如下:1.对于基于IP的低功耗有损网络路由协议RPL(IPv6RoutingProtocolforLLN),已有的组播路由算法存在大量冗余的数据传输,浪费节点有限的能量资源。
